1 Claim. 1

This invention relates to sprayer attachments for motor propelled tank trucks or trailers, or sprayers of any type, and more particularly to a sprayer attachment which can be readily applied to tanks of the type in general use for sprayer purposes, which tanks are generally provided with a longitudinally extending agitator shaft driven from some suitable power source, upon which shaft the agitator paddles are located within the tank, the rear end of this agitator shaft usually extending through the rear end wall of the tank.

An object of the invention is to provide an improved and simplified sprayer device which can be readily applied to such a sprayer tank and opn eratively connected to the agitator shaft so as to produce an oscillating movement ci the spray nozzles, spray guns, spray brooms or other spray discharge equipment, thereby directing such an oscillating fog or mist of spray as to effectively treat the trees in an orchard through which the tank thus equipped is propelled.

A further object of the invention is to provide a device of the character indicated of very simple construction, capable of being readily cleaned, or maintained, and containing a minimum of movable parts, thus reducing wear and breakage in operation.

A further object of the invention is to provide a device of the character indicated, in which the sprayer heads and nozzles or guns, brooms or the like, are located within the contour4 of the tank so as to be effectively shielded from the branches of trees between which the vehicle may be propelled.

Further objects will more particularly appear in the course of the following detailed descrip tion.

The invention consists in the novel construction, arrangement and combinations of parts hereinafter more particularly described and claimed.

One sheet of drawings accompanies this specification as part thereof, in which like reference characters indicate like parts throughout.

In the drawings:

Figure 1 is a rear elevation of the tank iltted with the present invention;

Figure 2 is a transverse horizontal cross section taken on line 2-2 of Figure 1;

Figure 3 is a vertical longitudinal cross section taken through the rear end of the tank on the line 3-3 of Figure 1; and

Figure 4 is a fragmentary side view of the end of the tank and the improved sprayer device in position thereon.

Referring to the drawings in which a simple embodiment of the present invention is illustrated, the conventional spray tank T is provided with a longitudinally extending agitator shaft i2, the rear end of which projects through the rear wall of the tank adjacent its bottom. As is usual in the construction of these tanks, the endv walls or headers H are set in from the ends of the side, top and bottom walls of the tank, and these projecting end margins of the side, top and bottom walls are utilized for securing to the tank a framework indicated generally as i, which comprises two U-shaped members 2-2 preferably formed from angle iron, the ends of these frame members being secured to the margins of the side walls of the tank as by bolts 36. These two frame members 2-2 are rigidly connected in parallel relationship by a rectangular plate il Welded or otherwise secured to the rear faces oi' these frame members, this rectangular plate 4 being formed with a forwardly extending bearing 6 for a stub shaft 'I which carries on its forward end toward the tank a sprocket wheel 8 over which a chain I!) is passed, which in turn passes over a sprocket wheel ll mounted on the agitator shaft l2. On the rear end of the shaft 'I is rigidly secured a face plate 9 provided with a plurality of circumferentially spaced threaded holes 2@ positioned at different radial distances from the center of the face plate and the shaft 1, so as to vary the stroke of the link I8, one end of which is adapted to be pivotally secured to the face plate 9, as by screw I9, which may be se lectively engaged as desired in one of the threaded holes 20.

Against the rear face of the plate 4 and in surface contact therewith is pivoted a second rectangular plate I6, the pivotal connection being provided as by bolt I3 which passes through suitable holes in the two plates 4 and I 6, and is secured as by nut I5 with suitable washers I4. The end of the link I8 is pivotally associated with the plate I6 as by screw l1 threaded in a suitable orice in the plate I6, offset with respect to the pivot bolt I3.

Secured adjacent the side edges of the plate IB, as by screws 22, are the bracket members 2| which are welded or otherwise secured to the spray headers herein illustrated as comprising a plurality of conventional pipe Ts 25 spaced as by nipples 23, one of which can be conventionally welded to the brackets 2|, the Ts accommodating the outwardly directed spray nozzle 24. At each end of each header, or at any desired position, elbows or Ts 26 are positioned, the bottom elbows accommodating the lowermost nozzle, while the upper elbow carries a nipple connected to flexible hose connections 21 which extend to ports 28 in the rear header I-I of the tank.

In operation it will be apparent that the rotation of the agitator shaft I2 will rotate the face plate 9 and through link I8 lwill :rock Athe rrectangular vplate I6 and thereby Sthe spray headers secured thereto by the brackets 2|. The brackets being removably attached to the plate I6, one of the headers can be entirely removed di desired, or both can be used simultaneously, as occasion requires. By connecting the KI8 to the face plate 9 in diieilertse'lect'ed vcritici-:1s 2li,l` the length of the oscillation stroke may be varied as desired.

When the spraying operation is nished, the simple removal of the bottom elbows 2B from the spray headers will permit the complete drainage of these headers andthe nozzles, and prevent the accumulation of sediment therein.

From the above description it will be apparent that the entire vdevice can :be very 4quickly assembled and positioned ion a spray machine merely by the boring of suitable .holes in the marginal overhang of the .side walls of the tank, as illustrated.

When desired, additional :rigidity can lbe provided .for the frame structure by an additional bracket 3l extending between the upper frame member 2 and the top 4wall of the tank, where it will .be similarly secured by bolt 30.

Various modications will readily suggest themselves to those skilled in the art, but within the scope of the Vpresent :invention as claimed.

Having thus `described my invention, I claim:

Sprayer attachment for -a tank of the Atype having a power driven longitudinally extending agitator shaft projecting therefrom, comprising a frame adapted to be secured to said tank, a xed plate vertically mounted at the front of said frame, a horizontal bearing carried by said plate extending rearwardly, a shaft in said bearing having a crank at its fore end and a sprock- =et at its rear end, said sprocket being adapted to be `chain connected .to a vgear ion the agitator shaft, a movable plate Lpi-voted `relative to said fixed plate and oscillatable in surface contact VA'therewith, a pitman between said crank and `movable :plate for oscillating the latter, similar rectilinear manifolds, means detachably secur- Aingfsaicl manifclds @to said movable plate parallel ltoeah other 4on opposite sides of the axis of rotation ci 'said movable plate, ilexible hoses connected -tosaid tank and respectively to said manifolds at one end, removable closures at the opposite ends of said manifolds, and nozzles carried by said manifolds communicating therewith.
